Question

Answer 1

Hint – We will start solving this question by noting down the information given in the question. Then we will divide the information in two generations, i.e., Generation 1 and Generation 2, which will help us solve this question and obtain our answer.

Complete step-by-step answer:
Here, it is given that a husband and wife have five married sons and each of them have four children.
So, using this information we can make a chart to make it easy for us, which is as follows:

Now, we will count all the members.
First we start with Husband and Wife, which is a couple, therefore,
Husband and Wife = 2 members ……………… (1)
Generation 1:
There are five married sons, so 5 couples, i.e., two of them each, therefore,
Total number of members in Generation 1 = 5 $ \times $ 2 = 10 members …………….. (2)
Generation 2:
Each of the five married son has 4 children, therefore,
Total number of children in the family = 4 $ \times $ 5 = 20 children ……………… (3)
Now, adding (1), (2) and (3), we obtain
2 + 10 + 20 = 32 members
Hence, there are a total 32 members in the family.
Note – These kinds of questions are very confusing sometimes, so it is better if we collect all the given information and by taking its help make a chart, which would help us to understand it quickly and easily.
